Should I be filming in Pal or Ntsc, to avoid flicker under artificial lighting ?

you may shoot in Pal for your region and switch to NTSC that may help out on the flickering, I shot last night and my dask lights do not flicker they go in and out and I am in NTSC I should try afjusting the shutter, nd filter and change htx ffrom 60 to 50 that will be Pal.
Other cameras have a flicker setting so you do not mess wit hthe preference, but gopro does not offer that. try out on a led , neon sign, flourencent light, or old glass tube tv. etc..

Japan is 50Hz, as Singapore, so use PAL.
folow the Japan link also from the below:
Special Notes for Japan
The frequency in Japan depends on your location. Eastern Japan (Tokyo, Kawasaki, Sapporo, Yokohama, Sendai) uses 50 Hz. Western Japan (Osaka, Kyoto, Nagoya, Hiroshima) tends to use 60 Hz.
here is a list of countries:
make a test!!!!!
to avoid flickering you have to match the PAL | NTSC with utility | line | mains frequency.
60Hz NTSC (30,60,120,240fps)
50Hz PAL (25,50,100,200fps)
you can use any multiple or submultiple of the frequency in fps.
the idea is the frames you capture to be in the same moment of the mains sinusoid wave.
1. I tried also 24fps when mains is 50Hz, does not flicker (being close to 25 = 50/2)
but 24fps at 60Hz I think will do.
2. even set up correctly, please be aware also at LED light systems that have an intensity feature.
in the kitchen, I have an Ikea with half power possibility LED under furniture.
here is what I get in my kitchen, 4K@50fps
hope this helps,

@robert1326 Since the effect of flicker is usually generated from filming indoors, I suspect the shutter was in the 1/48 - 1/24 range when you did your test. It will be interesting to know if this information is correct, so if you get a chance to test it, that would be great. Also test 30fps with a 1/30 shutter if you can.
@robert1326 Also, your link doesn't seem to be working, at least for me it didn't.
